While that's certainly an opinion, I'm willing to bet that real world child molesters do pretty much consume child porn (as they usually state in the news, "X man was caught preying on a child and was found to have child porn on their PC", it's a very repeated quote I find on news, see here as an example https://www.bbc.com/news/world-europe-isle-of-man-65419701 ).
So the argument we're trying to illustrate is that there definitely is a correlation between 'liking' those things, even in fiction (either AI or drawn) and then acting on them in real life.
I just don't buy it, honestly... and what's the need anyway? This is now just my personal opinion but I cannot fathom any artistic value in sexualising children. It's just pure malice and perversion to me (and we don't kinkshame in this house, but there are limits).
(also, no one here is arguing whether CP or the porn industry is worse, because they're both dreadful)
I'd just like to add as a fun thought on the topic, I think that there isn't such a big barrier between reality and fiction in our imaginations and brain processes. Say you want to go to the beach, at the moment that's fiction, untrue, because you're not in the beach, but you can be and make it real. You can also imagine yourself riding a unicorn on the Moon, that's also fiction, but cannot be fulfilled (probably, never been to the Moon to confirm). And the way this applies to this discussion is that preying on children is something that can happen, has happened, and will continue to happen so long as this rotten culture persists. They imagine it, crave it, and then go make it happen.
